FAW J6P Верхняя крышка: Деконструкция 31 Важнейшие детали для безупречного переключения передач

Welcome to this complete technical analysis of the FAW J6P Верхняя крышка сборка, а “command and control” center for the CA10TA160M manual transmission. Это руководство предназначено для FAW Jiefang CA3250P66K2L1T1E 6.×4 самосвал, deconstructing all 31 компоненты, from the main FAW J6P Верхняя крышка casting to every interlock pin and shift fork.

The FAW J6P Верхняя крышка это “мозг” of the manual gearbox. Its logic is to house the entire shift rail mechanism, translating the driver’s hand movements into the precise mechanical action of the shift forks. It also contains the critical interlock system that prevents mis-shifts and protects the gearbox from damage.

Основной 1: The “Структурная логика” (The FAW J6P Upper Cover)

Эта группа представляет собой основу “шасси” of the entire shift mechanism. Все 30 other components in this list are mounted *inside* or *onto* this single part, а FAW J6P Верхняя крышка.

1. Компонент: ‘Upper cover’ (1702026-A7G)
Этот (Комп 1) это FAW J6P Верхняя крышка сам. Это тяжелая работа, сложный компонент, прецизионное литье из железа или алюминия. Его логика тройственна.:

The Логика выравнивания это его самая важная функция. The FAW J6P Верхняя крышка is machined with multiple, perfectly parallel bores. Эти отверстия являются “туннели” that support the three main “Shift fork shafts” (Комп 17, 24, 29). Any warping or damage to this cover will cause the shafts to bind, making shifting difficult or impossible.

The Логика уплотнения это его вторая функция. This component acts as the “lid” for the entire gearbox, sealing the top opening of the main case and keeping the high-temperature gear oil contained. This seal is created by a gasket and the numerous bolts (Комп 5, 12, 15) that provide clamping force.

The Монтаж логики is its third function. The FAW J6P Верхняя крышка provides the threaded holes and mounting bosses for all the system’s sensors, like the ‘Neutral indicator switch’ (Комп 7) and ‘Reverse light switch’ (Комп 11).

2. Компонент: ‘Lifting lug’ (1702096-A7G)
Этот (Комп 14) is a heavy-duty steel bracket bolted to the FAW J6P Верхняя крышка. Его Service Logic заключается в обеспечении сильного, balanced attachment point for an engine hoist, allowing a technician to safely lift the entire, heavy transmission assembly out of the truck chassis.

3. Компонент: ‘Oil guide groove’ (1702083-A7G) & ‘Plugs’ (Комп 2, 6)
The ‘Oil guide groove’ (Комп 4) is a small but clever component inside the FAW J6P Верхняя крышка, designed to channel “splashed” oil directly onto the shift rails to keep them lubricated. The ‘Hex socket tapered plugs’ (Комп 2, 6) are used to seal any machining or service ports in the casting.

Основной 2: The “1st/Reverse” Shift Rail Logic (FAW J6P Верхняя крышка)

This group represents the complete mechanical assembly, housed within the FAW J6P Верхняя крышка, that is responsible for engaging First and Reverse gears.

1. Компоненты: ‘Shift fork shaft – 1st/Rev’ (1702041-A7G) & ‘Shift fork – 1st/Rev’ (1702046-A7G)
Этот (Комп 17 & 16) is the core 1st/Reverse linkage. The ‘Shift fork shaft’ (Комп 17) is the hardened steel rod that slides fore-and-aft inside the FAW J6P Верхняя крышка. The ‘Shift fork’ (Комп 16) is the rigid lever that is locked onto this shaft.

The Логика срабатывания это просто: the driver’s gear lever moves this shaft (Комп 17) forward or backward. The fork (Комп 16) moves with it, and its “зубцы” engage the ‘Sliding gear sleeve’ (on the Second Axis) to lock either the 1st gear or the Reverse gear.

2. The “Detent” Группа (Комп 18, 19, 20, 21)
В эту группу входят: ‘Plug – 1st/Rev shift fork’ (Комп 18), ‘Spring – plunger’ (Комп 19), ‘Plunger – 1st/Rev’ (Комп 20), and ‘Locking screw’ (Комп 21).

The Логика позиционирования is the function of this sub-assembly. The ‘Shift fork shaft’ (Комп 17) has three small “В” grooves machined into it (one for 1st, one for Neutral, one for Reverse).

The ‘Spring’ (Комп 19) pushes the ‘Plunger’ (Комп 20) with high force into these grooves. Это “detent” that gives the shift lever its “snap” и “щелкните.” It holds the gear in place and prevents it from popping out under load. This entire assembly is threaded into the FAW J6P Верхняя крышка.

Основной 3: The “2nd/3rd” & “4th/5th” Shift Rail Logic (FAW J6P Верхняя крышка)

This group contains the two remaining shift rails and forks, which are also precisely aligned by the FAW J6P Верхняя крышка.

1. The “2nd/3rd” Группа (Комп 23, 24, 25)
This includes: ‘Shift fork – 2nd/3rd’ (Комп 23), ‘Shift fork shaft – 2nd/3rd’ (Комп 24), and ‘Guide block – 2nd/3rd’ (Комп 25).

The Логика срабатывания is identical to the 1st/Rev rail. The ‘Shaft’ (Комп 24) slides within the FAW J6P Верхняя крышка, moving the ‘Fork’ (Комп 23) to engage the 2nd/3rd synchronizer sleeve. The ‘Guide block’ (Комп 25) is a small key that locks the fork to the shaft, forcing them to move as one unit.

2. The “4th/5th” Группа (Комп 28, 29, 30)
This includes: ‘Shift fork – 4th/5th’ (Комп 28), ‘Shift fork shaft – 4th/5th’ (Комп 29), and ‘Shift block – 4th/5th’ (Комп 30).

This is the final shift rail assembly. The ‘Shaft’ (Комп 29) slides in the FAW J6P Верхняя крышка, moving the ‘Fork’ (Комп 28) and its ‘Shift block’ (Комп 30) to engage the 4th/5th synchronizer sleeve. The ‘Shift block’ это “wear pad” that actually touches the ‘Sliding gear sleeve’.

Основной 4: The “Interlock & Датчик” Логика (The Safety System)

This group contains the “безопасность” features of the FAW J6P Верхняя крышка. Its logic is to A) provide feedback to the driver/ECU, and B) physically prevent a dangerous mis-shift.

1. The “Interlock” Группа (Комп 26, 27)
В эту группу входят: ‘Interlock steel ball’ (Комп 26, Кол-во 2) and ‘Interlock pin’ (Комп 27). These components are *not* detents; they are the “interlock” система.

The Логика безопасности это их функция. These small pins and balls sit in special cross-drillings *between* the three shift rails (Комп 17, 24, 29) inside the FAW J6P Верхняя крышка. When one rail moves (НАПРИМЕР., to engage 3rd gear), it pushes these pins and balls sideways. Этот, по очереди, *physically blocks* the other two rails, making it *impossible* for them to move from their neutral position. Этот FAW J6P Верхняя крышка interlock system is what prevents a driver from ever engaging two gears at once.

2. The “Detent” Группа (Комп 8, 9)
This includes: ‘Self-lock steel ball’ (Комп 8, Кол-во 3) and ‘Self-lock spring’ (Комп 9, Кол-во 3). This is the *main* detent system (separate from the plunger in Core 2). One set is used for each of the three shift rails. The springs (Комп 9) push the balls (Комп 8) into the V-grooves on the shafts, providing the “snap” и “click” feel for all gears.

3. The “Датчик” Группа (Комп 7, 11)
В эту группу входят: ‘Neutral indicator switch’ (Комп 7) and ‘Reverse light switch assy’ (Комп 11).

The Feedback Logic это их функция. These two sensors are threaded into the FAW J6P Верхняя крышка. Their plungers rest against the shift rails. When the 1st/Rev rail moves to “Reverse,” it depresses the ‘Reverse light switch’ (Комп 11), turning on the truck’s reverse lights. When all rails are in their center position, the ‘Neutral indicator switch’ (Комп 7) is depressed, telling the truck’s ECU (and the driver) that it is safe to start the engine.

Основной 5: The “Застежка & Уплотнение” Логика (All Hardware)

This final group contains all the remaining hardware that holds the FAW J6P Верхняя крышка together and secures the internal components.

1. The “Main Bolts” (Комп 5, 12, 15)
This includes: 'Болт с шестигранной головкой’ (Комп 5, Кол-во 2), ‘Hexagon bolt’ (Комп 12, Кол-во 2), and ‘Hexagon bolt’ (Комп 15, Кол-во 15).

The Логика зажима это их функция. These are the main bolts that fasten the FAW J6P Верхняя крышка (Комп 1) к корпусу главного редуктора, compressing the gasket (нет в списке) to create the vital oil seal. The ‘Spring washer’ (Комп 13) works with these bolts to prevent them from vibrating loose.

2. The “Internal Fasteners” (Комп 22, 31)
This includes: «Крепежный винт’ (Комп 22, Кол-во 5) и «Линия блокировки стальной проволоки’ (Комп 31, Кол-во 5).

The Critical Safety Logic is the function of this pair. The five ‘Fastening screws’ (Комп 22) are what lock the shift forks (Комп 16, 23, 28) to their respective shafts (Комп 17, 24, 29).

Because these screws are *inside* the FAW J6P Верхняя крышка, if one backed out, it would cause a total shift failure. To prevent this, they are “safety-wired.” Линия блокировки стальной проволоки’ (Комп 31) is threaded through holes in the heads of the screws (Комп 22) and twisted tight, making it physically *impossible* for the screws to ever vibrate loose.
